T0 @ZZ whom, t may concern.'

Be it known that I, CARLOS C. KELLY, of Olaysville, in the county of Guernsey and State of Ohio, have invented certain new and useful Improvements in Calendars; and I do hereby declare the following` to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it per-Y tains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

Myinvention relates to an improvement in calendars; and it consists in a calendar having the numbers of the years, the days of the week, and the months of the year printed. thereon in combination with movable strips having the names of the months and the days of the month marked thereon, the numbers of the months and the numbers of the years having figures extending' from 0 to G marked opposite them and which are to be used in finding the first days of the month, as will be more fully described hereinafter.

The object of my invention is to produce a calendar that is lgood for two hundred years, and by means of which the day of the week upon which any important event within that period occurred 4can be quickly found.

Figure 1 shows a calendar which embodies my invention complete. Fig. 2 shows the movable strip upon which the days of the month are printed.

A represents the calendar, which is printed upon any suitable material and which has the numbers for two hundred years arranged in any desired manner upon it. As here shown, the numbers for one hundred years are arranged along one edge and the numbers for the second hundred along,T the other, and the days of the week, the days of the month, the names of the months, and the directions for finding dates are placed in the center; but I do not limit myself to any particular arrangement in this respect, as this may be varied at will. The names of the months are printed upon a narrow slip B, which is movable back and forth through slits in the calendar, which are just near enough together to let the name of only a single month show at a time. The numbers of the days of the month are arranged upon a movable strip O in six rows, the first running from 1 to 7, the second from under any one of the days of the week and yet show the days fora full month. Opposite the numbers for the years are figures running from O to (i, and these figures are arranged in regular columns l, and opposite the names of the month are also figures, which run from O to G. For leap-years there is opposite Jauuary the figure 2 and February the figure 5. For the other years there isv 3 opposite January and G opposite February.

Directionsf-'lo find the day of the week on which occurred some important event in the past, or tofind on what day of the week will fall any holiday or other dates in the future, to the number opposite the year add the number opposite the month. It' the number. exceeds 7, deduct 7 therefrom; if the sum 1s O, use Saturday. For leap-years use the star numbers. Adjust the slip containing the numbers for the days of the month so that the day of the week corresponding to the above sum shall stand opposite the first day of the month.

VExamples-4f it is desired to find o n what day of the week September 1, 1891, will fall, add 1, the number opposite September to 2, the number opposite 1891,which makes 3, and this figure 5 indicates the third day of the week, which is Tuesday.

For December, 1890, add the figure 1 opposite December to 1, the figure opposite 1890, and we have 2, which represents the second day of the week, which is Monday, and then adjust the strip O accordingly.

To adjust the calendar for July, 1970, add 2 opposite July to opposite 1976, and we have 5, which represents Thursday, the fifth day of the week, and adjust strip so that the tlrst day of the month will come under Thursday.

To adjust the calendar for January-1892, add I2, the star number for January in leapyear, to 4-the number opposite 1892-and we have 6 for Friday. l

ATo adjust the calendar for August, 1890,
